GE IS200VVIBH1CAC Printed circuit board

ABOUT THE IS200VVIBH1CAC

The IS200VVIBH1CAC is a GE printed circuit board manufactured for the Mark VI system.  The Mark VI was one of several management systems for gas and steam turbines released by GE under the “Speedtronic” name.

The IS200VVIBH1CAC functions as a Vibration Monitor board.  This PCB processes vibration probe signals from the DVIB or TVIB terminal boards.  These probes connect directly to the terminal board.  Up to fourteen probes can connect to a board. The IS200VVIBH1CAC digitizes these signals and sends them to the controller via the VME bus.  Vibration probes are used for four protection functions, including: 

Vibration. 

Rotor Eccentricity.  

Differential Expansion. 

Rotor Axial Position

Main Functions

Vibration monitoring: The IS200VVIBH1CAC is capable of digitising analogue signals from vibration probes and sending them to the controller via the VME bus, enabling real-time monitoring of equipment vibration.

Protection functions: The board is equipped with a variety of protection functions, including vibration, rotor eccentricity, differential expansion and rotor axial position monitoring, to ensure the stable operation of the equipment.

Signal conditioning: It performs analogue voltage-to-voltage input and output conditioning functions, and is capable of converting a wide range of voltage input signals into conditioned output signals suitable for further processing or control.
